I think you made this one up!.
Simplify the following:
16-2×5+5^2+16/4^2-3×4/6+(15-13+1)^3
The gcd of 4 and 6 is 2, so 4/6 = (2×2)/(2×3) = 2/2×2/3 = 2/3:
16-2×5+5^2+16/4^2-3×2/3+(15-13+1)^3
4^2 = 16:
16-2×5+5^2+16/16-3×2/3+(15-13+1)^3
16/16 = 1:
16-2×5+5^2+1-3×2/3+(15-13+1)^3
(-3×2)/3 = 3/3×-2 = -2:
16-2×5+5^2+1+-2+(15-13+1)^3
15+1 = 16:
16-2×5+5^2+1-2+16-13^3
16-2×5+5^2+1-2+3^3
-2×5 = -10:
16+-10+5^2+1-2+3^3
5^2 = 25:
16-10+25+1-2+3^3
3^3 = 3×3^2:
16-10+25+1-2+3×3^2
3^2 = 9:
16-10+25+1-2+3×9
3×9 = 27:
16-10+25+1-2+27
16-10+25+1-2+27 = (16+25+1+27)-(10+2):
(16+25+1+27)-(10+2)
69-(10+2)
Answer: |57
